Abstract

1436951 Telemotor systems ENVIRONMENT/ONE CORP 13 June 1973 [16 June 1972] 28157/73 Heading F1P [Also in Divisions H2 and H5] In an induction cooker (see Division H2) the spacing between the induction heating coil L3 and the base of the cooking pot is adjustable by means of a flexible bellows 711, filled with hydraulic fluid and controlled by a flexible conduit 712 wound spirally on a control shaft 713. It is suggested that the temperature may be controlled by use of hydraulic fluid having a high temperature coefficient of expansion. In Fig. 8 (not shown) the coil L3 is supported by a large diameter hydraulic piston, coupled to a small diameter cylinder, the position of the piston being controlled by an operator.
